Boor’us Johnson, the UK’s proposed Prime Minister:

boor |bo͝or|
noun
a verbally flatulent, uncouth, ill-mannered person: the obnoxious boor had dealt the smug European Union a well deserved blow with his uncouth and belligerent manner.
ORIGIN mid 16th cent. (in the sense ‘peasant’): from Low German būr or Dutch boer ‘farmer.’

Just on the outside chance this proposed sobriquet will catch on ; )
